A hack of US government cloud email accounts blamed on a group linked to China raises questions about the New Zealand government's growing reliance on American data firms.
The government here is ordering agencies to use cloud computing - it has special relationships with Microsoft and Amazon - and some public tenders specify a preference to use them.
But Microsoft is now under investigation by the US Department of Homeland Security and a Senator accuses it of lax cyber security.
China rejects the accusations it was behind the hack as 'malicious'.
Reporter Phil Pennington spoke to Corin Dann.
